Simultaneous Communication and Tracking using Fused Bistatic Measurements
Avinash M, Srikrishna Bhashyam
In this paper, we propose a bistatic sensing-assisted beam tracking method for simultaneous communication and tracking of user vehicles navigating arbitrary-shaped road trajectorie…
Sequential Multi-hypothesis Testing in Multi-armed Bandit Problems:An Approach for Asymptotic Optimality
Gayathri R Prabhu, Srikrishna Bhashyam, Aditya Gopalan +1
We consider a multi-hypothesis testing problem involving a K-armed bandit. Each arm's signal follows a distribution from a vector exponential family. The actual parameters of the a…
Channel Conditions for the Optimality of Interference Decoding Schemes for K-user Gaussian Interference Channels
Ragini Chaluvadi, Bolli Madhuri, Srikrishna Bhashyam
The Han-Kobayashi (HK) scheme achieves the best known achievable rate region for the K user interference channel (IC). Simple HK schemes are HK schemes with Gaussian signaling, no…
Learning to detect an oddball target with observations from an exponential family
Gayathri R Prabhu, Srikrishna Bhashyam, Aditya Gopalan +1
The problem of detecting an odd arm from a set of K arms of a multi-armed bandit, with fixed confidence, is studied in a sequential decision-making scenario. Each arm's signal foll…
On the Sum Capacity of Many-to-one and One-to-many Gaussian Interference Channels
Abhiram Gnanasambandam, Ragini Chaluvadi, Srikrishna Bhashyam
We obtain new sum capacity results for the Gaussian many-to-one and one-to-many interference channels in channel parameter regimes where the sum capacity was known only up to a con…
On the Capacity of the Half-Duplex MIMO Gaussian Diamond Channel
Antony V. Mampilly, Srikrishna Bhashyam
In this paper, we analyze the 2-relay multiple-input multiple-output (MIMO) Gaussian diamond channel. We show that a multihopping decode-and-forward with multiple access (MDF-MAC)…
